Looking at the circuit board and mounting holes, it looks like the read head could fit straight on to replace one on the chopped digital calipers that hobbyists use as DROs.

The beam cross section dimension is the same.

There is even a cutout in the read head for the locking screw on a digital caliper, so these are probably used on ABS calipers as well.

The end result is that the existing chopped DROs would read much faster with the 3 volt read head.

Oh!?  :bugeye:
Not done anything with mine, yet. But, apart from the stiff slide compared to the normal digital glide, I've not found a problem!  :scratch:

Will have a closer look, this morning.......  :thumbup:

Marauder, who did you buy from?
I got mine from "ejoytune" off ebay UK. They haven`t arrived yet but I wonder if they are getting wind of the the sudden higher purchase order of these things and are ready to up the price?

Discard the tension spring - it's not required.

Bought mine from dealnts on eBay - no problems so far. You can see my build on my website.

Rob who designed this neat unit also commented on the situation with eBay dealers who must be very curious on the sudden rise in global demand.

Has anyone tried one of these with a DRO like the shumatech?

I know I`ve purchased single heads at near this price and they won`t work with my 350 shumatech - it would be even better if this one did.

As a Yorkshire lad myself I can appreciate your reluctance in discarding anything that has cost true brass.

What's going on ? ,dealants, like you say are out of stock so I ordered a second unit from another alledgedly UK company at £4.99, order was accepted and despatched with email confirmation - from dealnts ! Seems to be a Chinese co with stocks held in the UK. All very strange.

Incidentally these units have 3V batteries in the read head rather than the 1.5V batteries used in conventional digital calipers. When fitting remote DROs to my mill run from a transformer I had to go to great lengths to provide a dual voltage supply 3V for the DRO and 1.5V for the read head. Anyone now wanting to fit a similar system can use these 3V read heads and run it from one of those switchable mini transformers.

I ordered mine from "autoeshop" rather than "ejoytune", and got exactly the same messages from Emma as Chris did.

 :scratch: It looks like the same outfit is selling on Ebay under various names.

Hi Chris

UK Home Shopping, no URL but I think they are in Mansfield. Reckoned they had over 200 in stock (can't remember the exact number).

Let me know if you can't find them and I'll have another rummage.

I've just ordered two - to swap the read heads on the two 6" calipers I already have. One has failed and the other flashes no matter how new the battery fitted was. They also were quite slow in the displays.

A good guess would be that the dealer that has backed out on these deals and refunded the money has run out of stock, is telling everyone he can't bring himself to sell you rubbish, is getting more of the same in, and is going to jack up the price because these are "better quality units".

Or am I just cynical  ::)
